BIOS firmware archive for the Biostar B450MH desktop motherboard, version 6.3 according to the name, built for the AMD AM4 socket platform. The RAR is 14.2 MB and should be extracted before use to find the actual flash image. Technicians use such a dump to recover a board that fails to POST after a corrupted update by writing the SPI chip directly with a programmer such as a CH341A. Confirm the board revision printed on the PCB matches, read and save the original chip contents first, and check the image size against the flash chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
